LAKEWOOD, Colorado, April 6, 2017 /PRNewswire/ --Terumo BCT, a global leader in blood component, therapeutic apheresis and cellular technologies, today announced that the SpectraOptia® Apheresis System with therapeutic plasma exchange (TPE) has received the CE marked with an indication to treat Guillain-Barré syndrome (GBS) and myasthenia gravis (MG). The Spectra Optia system is a centrifugal therapeutic apheresis and cell collections platform and is the first and only device on the European market today approved to treat GBS and MG using TPE. GBS and MG are rare and debilitating orphan neuromuscular diseases. GBS has been associated with the Zika virus infection.
The expanded use indications were based on reviews of clinical studies supporting the safety and efficacy of TPE for treating GBS and MG. Various studies showed that by rapidly removing circulating disease mediators and immune complexes, TPE resulted in increased speed of recovery for the majority of GBS and MG patients when compared to supportive care. A single TPE procedure can rapidly lower all immunoglobulins (Igs).*
Spectra Optia TPE, also known as plasmapheresis (or PLEX/PEX), is a procedure during which a patient's blood is centrifuged to separate blood components, remove the plasma, and then replace the plasma. This procedure is recommended by the European Academies of Neurology and international consensus guidance as a safe and effective first-line therapy for patients with GBS and MG (pre-thymectomy, moderate to severe, crisis and refractory). TPE on the SpectraOptia system can be performed using peripheral vascular access.
The recently published international consensus guidance for management of myasthenia gravis (Neurology, 2016) stated, "Although clinical trials suggest that intravenous immunoglobulin (IVIg) and PLEX are equally effective in the treatment of impending or manifest myasthenic crisis, expert consensus suggests that PLEX is more effective and works more quickly."1
"We are pleased that Spectra Optia TPE is now CE marked with an indication that supports patients with these rare and debilitating neurological disorders, thereby enabling more treatment options," said Monte Smith, Vice President, Global Therapeutic Systems, Terumo BCT. "We are committed to further innovation in the field of apheresis therapies, with a focus on developing products that deliver life-saving treatment to patients."
*Immunoglobulins, also known as antibodies, are produced by white blood (plasma) cells. They act as a critical part of the immune response by specifically recognizing and binding to particular antigens, such as bacteria or viruses, and aiding in their destruction.
